Nitto NT01 225/40ZR18

225 is the tread width in millimeters, 40 means the sidewall is 40% of that width, and R18 is the 18-inch rim it mounts on. 88 is the load index (1,235 lbs per tire), and W is the speed rating (up to 168 mph).

Yes, the NT01 carries DOT approval, making it legal for street use. That said, it is engineered primarily for dry track competition, so everyday street driving is not where it shines brightest.

No. The semi-slick tread design is optimized strictly for dry surfaces, and the tire should only be used when temperatures are consistently above 45°F. Wet roads or cold conditions significantly compromise its performance and safety.

No, the NT01 uses a non-directional asymmetrical tread pattern. This means it can be rotated freely across all four wheel positions, giving you more flexibility in managing even tread wear.

Yes, the NT01 is suitable for both front and rear fitment. Many road course competitors run matched sets on all four corners for consistent handling balance.

The NT01 uses a specialized racing compound and semi-slick tread design that prioritize maximum dry grip over all-condition versatility. Unlike a typical UHP street tire, it is not intended for wet driving, cold temperatures, or year-round use — it is built to deliver repeatable lap times on a dry road course.
